Re: how to make the curve of the plot better?

Dear Wei,

It looks like you are plotting accumulated rainfall instead of rainfall
in mm/hour as indicated on your y-axis. The model will initialize that
accumulated rainfall to 0 at start of the model run or maybe even at
regular intervals. This is why your curve drops to zero at t=24h where
you have stitched together the two 24h files. I would suggest you
compute hourly differences from your data in order to get rainfall in
mm/hour.

Cheers,
Oli
